Abstract
An adsorbent includes core particles containing an adsorbing material; a porous coating layer including a polymer material that coats the core particles; and an underlying layer containing a metal compound and disposed between the core particles and the porous coating layer. The porous coating layer is formed by spraying and applying a suspension or a solution containing the polymer material over the adsorbing material, or by immersing the adsorbing material into the suspension or the solution.
Claims75
An adsorbent comprising:
- core particles containing an adsorbing material;
- a porous coating layer including a polymer material that coats said core particles;
- and
- an underlying layer containing a metal compound and a water-soluble polymer and disposed between the core particles and the porous coating layer, said water-soluble polymer being at least one selected from the group consisting of polymers of sugar, cellulose derivatives, alginic acid, methacrylic acid, acrylic acid, vinylpyrrolidone, vinyl alcohol, and oxyolefins.
An ambiance humidity regulating member, comprising core particles containing at least one humidity-regulating material of an acid, and a porous coating layer including a polymer material that coats said core particles, said acid being at least one selected from the group consisting of lactic acid, malic acid, tartaric acid, oxalic acid, chromic acid, dichromic acid, manganic acid, permanganic acid, thiocyanic acid, cyanic acid, carbonic acid, hydrochloric acid, perchloric acid, chloric acid, chlorous acid, hypochlorous acid, hydriodic acid, periodic acid, iodic acid, iodous acid, hypoiodous acid, sulfuric acid, sulfurous acid, nitric acid, nitrous acid, and phosphoric acid.
An ambiance humidity regulating member, comprising core particles containing at least one humidity-regulating material of an acid salt, and a porous coating layer including a polymer material that coats said core particles, wherein the acid salt is at least one of an alkali metal salt, an alkaline earth metal salt, and an ammonium salt.
